Hello all...picked up a '50s Robbins Myers today and was about to clean it's rusty cage in the electrolysis tank I use for my cast iron skillets when I stopped and thought about it. Then I started reading about cage cleaning here and the issues with different metals and coatings and wanted to ask a simple question. This cage looks galvanized, how is best to clean a 1950's RM cage safely and more than that...what is the rule of thumb for all cages. I'm trying to be safe so any advice would be.... yada yada yada. Thanks!

If I recall, they're cadmium plated, which is a carcinogen. So wear gloves, and a face mask if sanding it or wire brushing it. If there is no rust showing and it only is oxidized, a fine wire brush/ steel wool will shine it up. You can cleat coat it once clean if you'd like.
